ABSTRACT:
Cell storage and delivery systems and methods for storing and delivering viable cells to a mammal are disclosed. The cell storage and delivery systems include a biodegradable and/or bioabsorbable fibrous matrix physically associated with viable cells to contain and release the cells at a controlled rate. The biodegradable and/or bioabsorable matrix can be formed by electrospinning fibers of biodegradable and/or bioabsorbable fiberizable material. The methods include methods for storing viable cells and for delivering viable cells to a mammal using the cell storage and delivery system.
